Answer 1

Answer:

At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5

Step-by-step explanation:

At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5

since each interval contains equal number of values lets divide the data into 6 groups i.e.  frequency in the third group = 30 /6 = 5

hence we can say that the number of intervals used to test the hypothesis is 5

Answer:

x = 4

y = 4√3

tan 60° = 1.7321

Step-by-step explanation:

sin 30 = 4/8

0.5 = x/8

x = 4

y² = 8² - 4² = 64 - 16 = 48

y = √48 = 4√3

tan 60° = (4√3)/4 = √3 = 1.7321

17

Answer:

f(-2) = 3(-2)² - 2(-2) + 1 = 17

Step-by-step explanation:

f(x) = 3x² - 2x + 1

f(-2) = 3(-2)² - 2(-2) + 1

= 3 × 4 + 4 + 1

= 12 + 5

f(-2) = 17

Thus, f(-2) = 3(-2)² - 2(-2) + 1 = 17

No, the sum of the two smaller sides must be greater than the longer side.

In this case this would be just a straight line.

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

The given lengths won't form a triangle. The sum of the 2 smaller sides should be greater (not equal too) than the longest side.

so, the longest side her is 12ft

so the smaller sides are 4ft, and 8ft.

the sum of this two sides is 12ft which same as longest side (not greater)...

so it won't form a triangle, here it will just form points on lines.

A large firm that owns a chain of grocery stores wanted to see if they could increase the average number of patrons who visit by implementing a rewards member program. To test this, they randomly chose half of their 60 locations and started the rewards program only at those locations, while the other half of locations did not receive the rewards program. They also collected information the amount of money spent on these extra customers. Which of these answers represents an element of randomization in this study?

a. use a computer program to select the locations have a rewards program and those that don't
b. have an unbiased person just pick half of the stores to have the rewards program
c. allow store managers to volunteer

Answers

Answer:

a. use a computer program to select the locations have a rewards program and those that don't.

Step-by-step explanation:

Randomization refers to an important statistical procedure used to eliminate bias in a study. With randomization, all subjects in the study possess equal chances of being selected. In the study scenario described above, randomly choosing half of their total location to partake in the reward program would involve the use of a technique which isn't liable of introducing bias into the study either deliberately or systematically. The use of store managers or other human in the selection process won't be totally convincing at preventing bias. Hence, a computer program will do.

A large firm that has a chain of the grocery stores has implemented a reward member program to increase the visits of patrons. In order to check this, they test the same at 60 different locations.  

They do this by collecting information about the money spent and the number of customers Hence they use a computerized program that allows for asking reward programs and checks those who are eligible for the rewards.  The store manager of the chain store has placed such as system in place. This system is simple as it tracks those who have not yet got the rewards by checking their information.

Hence the option is A is correct.

Hi there!

[tex]\large\boxed{cos(\frac{\theta}{2} )= \frac{3}{\sqrt{7}}}[/tex]

[tex]\large\boxed{tan(\frac{\theta}{2}) = \frac{\sqrt{5}}{3}}[/tex]

Begin by recalling that:

sin(θ) = O/H,  so:

Opposite side = 3√5

Hypotenuse = 7

We can solve for the adjacent sign using the Pythagorean Theorem:

7² = (3√5)² + b²

49 = 45 + b²

b² = 4

b = 2.

Thus, cosθ = 2/ 7

Use the half angle identity to solve for cos(θ/2):

cos(θ/2) = √(1 + cosθ)

Plug in the value of cosθ:

= √(1 + 2/7) = √9/7, or 3 /√7

Thus:

[tex]cos(\frac{\theta}{2}) = \frac{3}{\sqrt{7}}[/tex]

Calculate tan(θ/2) using the same process but with a different formula:

tan(θ/2) = √(1 - cosθ / 1 + cosθ)

Substitute in the value of cosθ:

tan(θ/2) = √(1 - 2/7)/(1 + 2/7)

= √(5/7)/(9/7) = √5/9 = √5/3
